Abstract:

For the stress-strain apparatus introduced in section 2.1, the errors are ±2.3% for Young’s modulus, ±1.8% for Poisson’s ratio and ±0.008 for Young’s attenuation and Poisson’s phase difference. Text S1-S2 and Figure S1-S2 show the calculation of the error. In addition, there is residual brine in the sample as the sample is saturated with oil. Therefore, there might be the mesoscopic flow – typically as patchy model- during the experiment. Text S3 and Figure 3 investigate the influence the mixture fluid on the attenuation and dispersion based on White’s model incorporating Dutta Ode correction. Tables S1 to S2 are the parameters used for the prediction.
